Sorry I missed your post from earlier this month Travis. I'll have to check my account here and see if it's setup for email notifications... but to answer your questions:

All three of the current MSPNP models for Miatas (90-93, 94-95, and 96-97) are running the MS-1 processor. The MM9093 and MM9495 models run the standard MS1 Extra firmware, and the MM9697 runs the HiRes MS1 Extra firmware. For those familiar with MegaSquirt these details are of course available. For those that just want it to work though, when you install the MegaSquirtPNP software package from the included CD-ROM or from the download link here (http://www.megasquirtpnp.com/mspnp_downloads.htm) the software is properly setup for your specific MSPNP model and you don't have to worry about what firmware version you are running unless you just want to know, or go out on your own and update it. (for example some of the MM9093 and MM9495 guys have ventured out and installed the HiRes firmware on these models, works fine of course)

The install is incredibly simple. Maybe an hour if you goof around. Check out the 'Quick Start Guides' for the install process in a nutshell on this page: http://www.megasquirtpnp.com/mspnp_installation.htm

That also has the full manuals linked ^^


Joe Tenney (ITA Miata #16) came by the shop today actually. We installed a unit in his car and I tuned it out for him. I pulled 3 comparo graphs before we did anything with his stock ECU in place with tweaked AFM, and have before and after comparison charts. I think Joe's pretty pleased. I'll post charts soon but figured I'd give him a chance to share if he wanted to.
